Installation
Locate the unit on a sturdy work area. Ambient
temperatures should be inside the range of +50°F to
+104°F (+10°C to +40°C). The maximum operating
relative humidity is 80%.
Never place the unit in a location where excessive
heat, moisture, or corrosive materials are present.
Make sure the voltage of the power source meets
the specified voltage, ±10%.
The pump connections are located at the rear of the
pump box and are labelled
connections are angled upward so the recirculating
fluid will drain back into the reservoir when the
hoses are disconnected. Both connections are
capped with stainless steel serrated plugs.
The pump lines have ¼" MPT for mating with
standard plumbing fittings. For your convenience
